Because that is what is really in the font.

Because Windows allows you to use many other mappings. However, it resolves
it internally, and it accesses only the Unicode encoding in the font.

You can do the the same thing in Windows, using MultiCharToWideChar (or
something like that) API.

You should be able to access them without any problem, providing you
give their proper Unicode code points, not the codes Windows uses
in the 0x80-0x9F range.


Hope it helps,
